This'inven'tion relates -to a device for the )reservation-or" perishable substances such as food, etc, by removing the surroui'iding air, and has for its principal object, the proa vision of a gasket for a container lid which will 'aiitoinatically' insure anair tight'joint between the container and the lid.

Another object of the invention is to provide a device in which the natural suction of an automotive engine maybe employed for removing the air from the container.

A further object is to providea series of .sh'elvesin a container of this typefwhich may be readily removed from the container to'reach the contentsthereof.

Other objects andadvantages reside in the construction employed to obtain a highly efficient, air-tight container for this purv pose and in the method'used tor incorporating a pump in t-he'device' These objects and advantages will become more apparent "from the following description. T

"in the following-detailed description of the invention, reference is had to the accompanying d awings Which form a part hereor". -Like numerals refer to like parts in allvi-ews of the drawingsand throughout-the descrip tion. l In the drawings;

Fig. 7 is a vertical cross section, taken Fig. 6.

8 is a detail View of the gasket construction employed in the container.

Fig. 9 is a detail view of the gasket'band. The invention comprises a container 10, provided with a surrounding gasket ring 11, spaced from the container by an annular spacer 12 whichis secured to both the container and the band 11. A lid 13 having an annular rim closes the container. The pc- 5 riphery of the rim 1 1 rests upon a deep is a vertical cross section through rubber gasket 15 contained in the gasket ring 11. I

I Extending across thc lid-13, and secured thereto, is a clamping bar lfiterminating'in bifurcated extremities. Clamp bolts 17 are secured in lugs 18 on the gasket ring 11 and enter the bifurcated extremities of thebar i 16, being clamped'theretoby meansof Wing nuts 19. This arrangement removes all strainv from the container since the tension "of the bolts 17' is distributed between the lidand the gasket ring. 7

Upon the lid 13, a pump cylinder 20 is carried onlegs 21 and 22,1 the le 22 being hollcw and acting as an intake to the pin-11p cylinder. The leg 22- terminates in a ball valvcQS arranged to allow air to be drawn from the container 10 but preventing its return thereto. A cupped piston 2% is operarea within the cylinder 20, by ineansol a pump handle 25. j r

Within the container 10; a series of angle clips 26 are secured atspacedintervals, upon. which, circular shelves '27 rest. In theedge of each of the shelves 27.,a series of notches 28; are formed, corresponding in spacing to "the spac ng'of the CllPS'QG, thus, by rotating the shelves until the notches 28 align with the clips, the shelves may be lowered or raised "from the container, Either one, both, or neither of the shelves may be employed as desired. "lVhen not in use, the shelves maylie in the bottom of the icontainer. r

A central opening 29 is tormedin each of the shelves to allow theinto beer-upped for removal. To facilitate removal, I employ a handle, as illustrated in'Fig. .5, comprising a Hat strip of spring metal 30 bent in a U-shape with oppositely extending feet- 31. By compressing the U, it may be passed through the opening 29 and allowed to expand against the sides of the opening. The feet 31 will then lift the shelf from place.

In Fig. 6, I have illustrated an embodi- .ment of the invention inwhich the'vacuum ployed as a food container for automobile touring and camping. The automobile is illustrated in outline at 32, the engine thereof at. 33, and the intake manifold at 34.

The container in this instance may be placed ill) under the rear deck 01 the automolnle or under a seat thereof and is connected, by means of a pipe 3:) controlled by a valve 3b. to the intake manifold 23 i. lVhcre the pipe 35 enters the container, a ball valve 38 is placed to allow air to be drawn thereil'rom but preventing its entry. The pump cvL inder 90 may be embodied in this :l'orm to remove the air 'lrom the container when the engine is not in use. A relieil valve 37 is used to break the vacuum in the container so that the lid may be removed.

In Pig. 8, I have illustrated an alternate :lorm of the gasket ring. In this form. a gasket band 38 emploved in which the gasket ring' and floor are termed as an intcg'ral. part. lhe band 30 soldered or welded to the container and carries the gasket rubber against which the lid 'llane c l-Ll rests.

it is desired to call especial attention to the gasket construction employed in the de vice. The llerible gasket is relatively deep in the direction of pr sralllt! and relatively narrow at right angles thereto so that pressure on the lid will tend not only to :lorce the gasket into its seat but will also expand it in all directions, thereby insuring a perfect seal. The gasket rubber is preferably made with a greater length than the cricuinference ol. its groove so that when in place. it will be under a natural compression which will expand against the walls of its seat. The novel position of the gasket removes the necessity for properly centeringthe lid thereon since the lid slides snugly on the exterior of the container into contact with the gasket.

The invention has been iiouud also valuable :lonkeeping paints, varnishes, and paint and varnish brushes from dryins r or hardchina and is an im novement over applicants ciinpcnding application, Serial Number liltidltlll, for a device for preserving perishabl substances.

\Vhile a Specific form of the improvement has been described and illustrated herein, it is desired to be understood that the same may be varied, within the scope of the ap pended claims, without departing from the spirit of: the invention.

Having thus described the invention, what I claim and desire secured by Letters Patent isz- 1. In a vacuum preserving device comprising a container and a lid for said container, a grooved ring surroinuling, and secured to said container adjacent its top; a flexible gasket carried in said groove, said gasket extending above said ring; a rim :tormcd on said lid and adapted to slide on the con tainer oll into contact with the above extending; portion ol said gasket.

In a vacuum preserving device comprising a container and a lid :lor said container, a grooved ring surrounding and so cured to said container adjacent its top; a l'lexiblc gasket carried in said groove, said casket extending above said ring; a rim llii'illld on said. lid and adapted to slide on the conlainw wall into contact with the above extending portion of said gasket, said gasket. being relatively deep in the direction ol the pressure of said rim and relativizaly narrow at right angles thereto.

3 In a vacuum preserving device comprising a container and a lid :lt'or said container, a grooved ring surrounding and secured to said container adjacent its l'o a llexible gasket carried in said groove, said, gasket extending above said ring; a rim l'ormed on said lid and adapted to slide on the container wall into contact with the above extending portion of said gasket, said gasket having a greater normal length than the circumterence of said ring so that when in place it will be under compression; and means For d rawiug said lid toward said con-- la i nor.
